What This Part Is Used For

Tesla’s Active Hood system is designed as part of pedestrian protection. In a qualifying front impact, the system may raise the rear portion of the hood to create additional space between the hood and hard components beneath it. This actuator is part of that safety system, so the page should treat it as a repair part, not as a normal exterior accessory.

• Safety System Component: Related to active hood deployment, not ordinary hood opening.
• Diagnostic-Driven Replacement: Should be replaced only after proper inspection and fault diagnosis.
• Post-Deployment Service: Active hood sensors and actuators require service after deployment.
• Professional Repair Audience: Best page audience includes repair shops, body shops, technical buyers and experienced EV service teams.

Position This As A Repair Part, Not A General Accessory

Customers buying this part are not looking for style or comfort. They need to confirm the correct replacement part quickly and confidently. The page should prioritize part number, real product photos, connector detail, fitment verification and safety service notes.

• Lead With OE Number: Show 1735702-00-A clearly in the title, first image and buying area.
• Use Technical Naming: Active Hood Actuator / Pedestrian Protection Actuator is clearer than “Hood Airbag.”
• Show Every Angle: Front, rear, side, label, connector and mounting ears should be visible.
• State Service Requirement: Professional diagnosis and installation required.
• Reduce Wrong Orders: Add “VIN verification required” above the Add to Cart button.

Fitment Must Be Verified By VIN And Part Number

Repair parts should not rely on broad model names alone. Active hood systems can vary by model year, market, production configuration and repair history, so customers should confirm exact compatibility before checkout.

Connector And Label Photos Are Critical

The updated image set already includes multiple real part angles, which is good for conversion. For a repair component, customers need close-up views of the connector, label, mounting holes and warning markings to compare against the removed part.

• Connector View: Helps customers compare the yellow plug shape and pin layout.
• Label Area: Helps confirm printed part number and production marking.
• Mounting Ears: Helps compare bracket shape and bolt-hole position.
• Cable Loop: Helps identify the correct actuator style and harness direction.

Clean Up Overstated Claims On The Current Page

The current product copy says the system uses radar and sensor dual judgment and is only triggered by the human body. That is too absolute for a safety system and should be removed. A safer, more accurate page should explain that Active Hood deployment depends on vehicle sensors, calibrated algorithms and the actual collision conditions.

• Avoid: “Only triggered by the human body.”
• Use: “Part of Tesla’s active hood pedestrian protection system.”
• Avoid: “Non-destructive installation, no need to modify wiring.”
• Use: “Professional installation following service procedures required.”
• Avoid: “Significantly reducing pedestrian injuries” as a direct product promise.
• Use: “Replacement component for the active hood pedestrian protection system.”

Installation & Service Notes

This component should not be described as a normal DIY accessory. Active hood actuator replacement involves safety system diagnosis, controlled disassembly and correct reconnection of the pyrotechnic actuator connector.

• Diagnosis First: Confirm the issue with proper Tesla-compatible diagnostics before replacing the part.
• Service Procedure Required: Follow the correct Tesla service procedure for the exact model and year.
• Power Safety: Required vehicle power-disconnect procedures must be followed before working around the actuator connector.
• Correct Side / Position: Confirm whether the vehicle requires this exact actuator and location.
• Fastener Torque: Use correct torque specifications from the service manual.
• Post-Repair Check: Confirm no active safety warnings remain and verify related system status after installation.
